New Clustering Features

Beaver also credits a couple of new clustering features with helping to speed
the move. "We have a very large SQL database. Through log shipping, we were
able to keep 20GBs of it available during the cutover. Then we used distributed
transaction processing for migrating the data with SQL replication. The net
effect? Nothing went down."

The upgraded Microsoft Distributed Transaction Coordinator (MDTC) in W2K3
adds the capability to replicate to multiple nodes through only a single change
in configuration, Microsoft says.

Log shipping, on the other hand, is made possible by W2K3's optional
quorum resource, which does not require a disk or shared bus for the quorum
device. Techniques such as log shipping can then be used to make more data
available on multiple nodes in a cluster.

About 8 to 10 technicians teamed up for the September migration, including
staffers from both eNom and PDC, eNom's new hosting partner.
